Question

12．In its first ever National Building Competition，the U．S．Environmental Protection Agency （EPA） challenged the teams from across the nation to cut wasteful energy use in buildings where they live and work．Family and commercial ladings together consume 40 percent of U．S．energy and the Obama Administration is eager to show how that load can be reduced．
In recent remarks at a university．President Barack Obama promoted a plan that could help commercial buildings achieve greater energy efficiency （效率）．
"Making our buildings more energy-efficient is one of the fastest，easiest and cheapest ways to save money，fight against pollution and create jobs right here in the United States of America，"he said．He also inspected the research labs where scientists are working on new technologies designed to cut energy waste in commercial buildings．
Stores like the Sears department store in Maryland，which took second prize in the contest，are already using some of those technologies．As part of the store's bid to cut its energy use，every one of the building's 24 rooftop AC （交流电） units was checked and repaired．Every light bulb-all 15，000 of them-was replaced with a more efficient one．And sensors were installed （安装）to shut lights off in offices and storerooms when no one is around．Taken together these changes helped the Sears store reduce its building energy consumption by more than one-third and cut electric bills by $ 46，000．
Office buildings can also achieve impressive energy savings．The tenants of a 12-story building in Virginia managed to cut the building's energy consumption by 28 percent as part of the EPA competition．
"Whether it's an office building or a department store，a school or church，the EPA energy challenge showed that there's always room for improvement"，says Jennifer Amann with the American Council for an Energy Efficient Economy，
71．The purpose of the Competition is toA
A．help cut buildings'energy waste                        
B．fight against air pollution
C．create more job opportunities                           
D．experiment with a new idea
72．Which of the following is true according to the text？B
A．Forty percent of the U．S．energy is wasted．
B．Scientists are developing new technologies for energy efficiency．
C．Efficient bulbs are now being used in all American buildings．
D．Family buildings consume more energy than commercial ones．
73．The Sears department storeA
A．used new technologies to cut its energy waste
B．won the first prize in the Competition
C．cut its energy consumption by 28 percent
D．had 24 rooftop sensors installed on the building
74．The 12-story building in Virginia mentioned in the text should be a（nC
A．department store                                        
B．commercial building
C．office building                        
D．family building
75．From what Jennifer Amann says，we can infer thatC   
A．the awareness of energy efficiency has highly improved
B．energy savings will benefit the whole world
C．all buildings can be energy-efficient if changes are made
D．the government is responsible for energy waste．

Answer 1

分析 在首届全国建筑竞赛上，美国环保署要求来自全国各地的参赛小组最大幅度地降低人们工作和生活于其中的建筑的能源浪费．居住和商用建筑消耗能源占全美能耗总量的大约百分之40．建筑物消耗大量能源．这就是为什么奥巴马总统2月初前往宾夕法尼亚大学，推动一个可能帮助商用建筑提高能效的计划．

解答 71．A 根据第一段第一句In its first ever National Building Competition，the U．S．Environmental Protection Agency （EPA） challenged the teams from across the nation to cut wasteful energy use in buildings where they live and work．可知，此次竞赛的目的是降低楼房的能源浪费，故答案为A
72．B 根据He also inspected the research labs where scientists are working on new technologies designed to cut energy waste in commercial buildings．可知科学家们正研制新的技术用来节能，其余选项不符合文意，故答案为B
73．A  根据Stores like the Sears department store in Maryland，which took second prize in the contest，are already using some of those technologies．可知the Sears department正在使用新的技术来节能，故答案为A
74．C 根据Office buildings can also achieve impressive energy savings．The tenants of a 12-story building in Virginia managed to cut the building's energy consumption by 28 percent as part of the EPA competition．可知The 12-story building in Virginia应该属于办公楼，故答案为C
75．C 根据"Whether it's an office building or a department store，a school or church，the EPA energy challenge showed that there's always room for improvement"，says Jennifer Amann可知，不论是哪里的建筑，所有建筑物都应该采取节能措施，故答案为C．

点评 做阅读时经常犯错的主要原因是，仅凭读过文章后残留在脑海中的一丝印象来勾选答案，这样便很容易掉入出题人故意设布下的题目陷阱．所谓阅读理解，对于题目的理解一定要忠实于原文，因此，每一道题都应该与原文作全面的对比与核查，再得出答案．也就是说，阅读理解的每一道题目，在原文都应该有明确的出处，我们把这一出处叫做原文相关句，（1）排除与原文相关句主题不一致的选项（2）排除与原文相关句态度相反的选项  （3）排除用于过于极端或负面的选项（4）注意结合文章主旨和主题去排除．
